Title: Performance Analysis using Contention Based Queueing Model for Wireless Sensor Networks
Authors: R. Maheswar and R. Jayaparvathy
Abstract: A critical issue in wireless sensor networks is the limited availability of energy and hence optimizing energy is very important. In any sensor node, most of the energy is consumed during packet transmission. We propose a new scheme to reduce the energy consumption of nodes during packet transmission based on queue threshold. We develop an analytical model of a cluster based sensor network by taking channel contention into account and analyze the performance of the proposed scheme in terms of performance parameters such as average energy consumption and mean delay. We also derive the expression for the optimal value of threshold. Results show that the average energy consumption reduces by 68% for the optimal threshold value when compared to no threshold condition by considering mean arrival rate per cluster head of 4 and there exists trade-off between the average energy consumption and mean delay. We perform simulations and the results obtained show that the analytical results match with the simulation results thus validating the analytical model
